If I choose a standardized language that I use: Verilog, and compare it
to Python then I find that Verilog has a a standards document, but in
practice their are many grey areas that means problems occur when using
different Verilog tools, from different vendors.
Python has its Language reference, its tutorial, and a test suite
freely available. CPython, the interpreter written in the C language of
Python is tested against the test suite as are other imlementations:
Jython - Python in Java bytecodes; or IronPython:- Python for dot Net
or more experimental versions of Python such as PyPi - Python written
in Python.
The intended behavior of all the implementations would be to pass the
freely available test-suite.

So, for a language implimentor, (which I am not), wouldn't a spec' plus
test suite, plus reference implimentation be much more help than spec
alone?
